Custom sounds alerts for mms,text, and alarms?

I loaded up some ringtones on my 760 tonight, but cant for the life of me see where you can use any of those cutom tones for anything other than a phone call. Is it possible to use custome tones for message alert or even for an alarm. Im still using my old for the alarm to wake me up, because the 760 just gives off a little beep and no snooze option. How can I change this? Please help.
